. RAILWAY-RAIL.

SPECIFICATION forming part of Letters Patent No. 276,242, dated April24, 1883. Application tiled October 5, 1882. (No model.)

ATo all whom. t may concern Be itA known that I, JOHN F. HANLON, asubject of Great Britain, residing at Boston, in the county ot' SuEolk,State of Massachusetts, United States of America, have invented acertain new and useful Im provement in Rail- Way-Rails, of which thefollowing is a description suciently full, clear, and exact to enableany person skilled in the art or science to which said inventionappertains to make and use the same, reference being had to theaccompanying drawings, forming a part of this specification, in which-Figure l is a side elevation; Fig. 2, a plan or top view; Fig. 3, abottom view; Fig. 4., an isometrical perspective view, showing the partsof the joint detached; Figs.` and 6, vertical transverse sections oftherails, taken through the joint ,and Fig. 7, a vertical transversesection taken through one of the fish-plate bolts.

Like letters of reference indicate correspond' ing parts in thediii'erent figures otlthe drawings.

My invention relates more especially to the joint ofthe rail; and itconsists in a novel construction and `arrangement of parts, ashereinaftermore fully set forth and claimed, by which a more effectivedevice of this character is produced than is now in ordinary use.

The nature and operation of my improve- Y ment will be readilyunderstood by all conversant with such matters from the followingexplanation, its extreme simplicity rendering an elaborate descriptionunnecessary.

In the draWings,A B represent the rails, which are of full thickness orrectangularin cross-section at the joint and connected in the usualmanner by the fish-plate C and nuts and bolts d. The joint proper isformed as best seen in Fig. 4, the rail B being provided with thehorizontally-projecting flanges m x, and l vwith the V-shaped projectiona, and the rail A with the rabbetg, space or mortisef, and V- shapedslot Z, into which the projections zc, m, and a respectively enter whenthe rails are united, as shown in Fig. 1.

It will be obvious that informing the spaces g f a flan ge, n, isnecessarily produced, and that a corresponding slot or space, t', willbe left in forming the anges m w, in which the Bange 91.

will rest when the rails are connected.

It will also be obvious that in rails provided I With my improved jointthere is no especial necessity for the use of chairs.

The rail is also substantially continuous, as a car-wheel in passingfrom A to B will pass onto the V-shaped'projection a before it leavesthe rail A, and vice versa.

Having thus explained my improvement, what I claim is` The improvedrailway-rail joint described, the same consisting of the rails A B andplate O, the rail A being provided with the V-shaped slot l, spacesj'g,and flange n, and the rail B with the V-shaped projection a, space t',and anges m w, all constructed, combined, and arranged to operatesubstantially ais specified.
